The increase in piping size decreases back pressure allowing the 135iís turbo charge to spool even faster resulting in increased horsepower and torque throughout the entire RPM range. Our engineering team also incorporated the Active Autowerke SIGNATURE MuffleR in this new GEN II to assist in reducing/eliminating drone in the BMW 135i exhaust even more than our previous GEN I. Manufactured from 100% polished 304 stainless steel, true bolt on system.

Im new when it comes to this forum and i have never done a group buy. I was wondering if i had to wait till the end of the group buy to receive the exhaust or as soon as i pay it will be shipped? also wondering if what are your methods of receiving payments for the product?

I've searched, might have been easier to post a link to one if you know you've sent a few out already...I'm looking for a stock N55 setup with a Gen II drive by.

Ready to buy one as soon as I hear it, but until then I can't buy it for risk of it being too loud/droning.

Completely understandable, unfortunately all the cars that we have received with this exhaust at our shop have been N54s so far. We haven't received any videos or sound clips from our N55 customers yet. Hopefully we will soon.

Hey, I just installed the GEN II exhaust on my N55 this past weekend with the help of a buddy. Manny asked me to post some videos, they aren't the best but they are better than nothing. Realize that this is also with the active autowerkes catless downpipe and the stock N55 midpipes.

Quality is top notch and fitment was excellent. I consider myself a novice when it comes to bolt-ons but the quality made it really easy for me to install. Definitely recommend! A++
